Building the Agent Economy

We're thrilled to announce the launch of NullState — the first open-source, multi-protocol payment and settlement layer purpose-built for AI agents.

The Problem​

AI agents are doing real work — coding, trading, researching, automating. But they have no native way to pay each other or get paid. Every transaction requires a human in the loop.

The agent economy settled $73M in the past 12 months via stablecoins, with 176M transactions at an average of $0.31. But every one of those required human intervention.

The Solution​

NullState is a self-hosted commerce layer that gives AI agents their own payment infrastructure:

  • x402: HTTP 402 crypto micropayments via USDC on Solana
  • AP2: Enterprise agent-to-agent mandates with RSA-2048 dual-signature
  • MCP: Model Context Protocol integration — 5 tools, 2 resources
  • KYA: Know-Your-Agent identity verification

Why Now?​

The market is exploding:

  • Stripe launched their Agent Toolkit (Feb 2026)
  • Coinbase launched AgentKit with x402 integration
  • AEON raised $8M for the same concept
  • 104,000+ agents registered across 15 directories
  • $93B projected market by 2032

Every competitor is centralized SaaS. NullState is open-source, self-hosted, and non-custodial — your keys, your infrastructure.

What's Next​

  • VS Code Agent Workspace Plugin — sandboxed terminal for AI coding agents
  • Gemma 3 27B fine-tuned model — purpose-built for protocol operations
  • Managed Gateway-as-a-Service — for teams that want hosted NullState

Check out the docs, star us on GitHub, and deploy in 30 seconds.

The agent economy needs payment rails. NullState delivers.
